MECHANICAL MOVEMENT.

Monaca.

fo all whom it may concern Be it known that I, WILLIAM W. WILSON, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented new and useful Improvements in Mechanical Movements, of which the following is a specification.

lThis invention relates to mechanical movements whereby rotary motion may be translated into reciprocatory motion, or vice versa; and the invention has for. its object to provide an improved mechanical movement of this characterwhich will be relatively simple and inexpensive in construction and organization, which maybe conveniently and satisfactorily constructed in the main out of stock materials and machine elements, which will be positive in operation, economical in consumption or loss of energy, which will be compact in form, which will be capable of long continued operation without appreciable deterioration or wear of workingl parts, whichr will be convenient in installation and assemblage and disconnection of parts and features for substitution or repair of parts, and which will be generally superior in efficiency and serviceability. y y

In a preferred form, such as shown in the drawings and hereinafter particularly described, the invention provides an improved Y mechanical movement particularly adapted for pump actuation, and for the actuation of pumps having a plurality of pistons, valves or valve-carrying pistons, which lat-ter are oppositely actuated during simultaneous phases of their reciprocations.v l

`With the above and other objects in view, the invention consists in the novel and luseful combination, inter-relation and operative association of parts, members and features, together with the provision, construction and formation of such parts,y members' and features, all as hereinafter described, shown in the drawings and finally pointed out in claims.

In the drawings z-Figure l is a side elevation of mechanism organized in accordance with the invention ,'FiggQ, is an end elevation of the same, looking in the direction of the arrow in Fig. l; and, Fig; 3 is a top plan view of the showing in the other figures.

Corresponding parts in all the figures are denoted by the same reference characters.

Referring with particularity to the draw- Specficaton of Letters Patent.

ings, the improved mechanical movement is shown therein as comprising in its embodiment a rotating member A, reciprocating members B and C respectively, and motion translating means l) between and operatively connected with said members A, B and C, and whereby the motion of the rotating member A may be translated into reciprocatory motion of the members B and C; and whereby the reciprocatory motion of either or both of said latter members may be translated into rotary motion of the member A. Specifically, the motion translating means D are shown as organized to produce simultaneous phases of movement of the `members B and C in opposite directions, in the reciprocation of said members B and C. Further, specifically, the member B is shown as connected-up with a pump rod E; and the member C is shown as connected up with a pump rod or sleeve F, the pump rod being housed operatively to `play within the pump sleeve, and said pump rod and pump sleeve carrying respectively at their lower ends pump pistons or valves or val-ved-pistons, the latter not being shown as not being concerned in the issues of the present invention, but only being referred to as exemplary of particular uses for which the improved mechanical movement is adapted. The pump rod and pump sleeve are shown as extending downwardly through a stuiiing box 4 at the top of a well casing` 5 from which, above the mouth of the well, extends laterally a main pipe through which the elevated Huid is discharged.

ln the specific organization and arrangement of parts, members and features illustrated in the drawings, the rotating or rotary member A is shown as initially actuated to produce reciprocation of the reciprocatory members B and C; such rotary member A receiving its actuation from a prime mover or source of power Cr illustrated as a shaft 7 upon which is mounted a fixed pulley 8 rotated by a belt 9 extending to suitable motive means and producing rotation of the shaft 7 in a constant direction.

Coming down to a consideration of specilic members, elements and features, such `as those shown in the drawings, yfor embodying the improved mechanical movement, the member A may, as illustrated, comprise spaced gear wheels l() mounted uponL a shaft 1l iournaled at its ends as at 12, upon parallel longitudinal frame or base members 13, suitably disposed'and anchored' so as to span a pit l-l at the bottom of which the well casing 5 terminates just above the mouth of the well. Pinions 14: uponV the shaft 7 mesh respectively with the gears 10, such shaft being journaled at its ends as at 15, upon the members 13. More directly in vertical alinement with the top of the well casing 5, and centered respectively in vertical planes between which such casing top is located, are disposed pairs Vof toothed sectors 15 and 16, the sectors of each pair being spaced apart and mounted'upon a separate shaft, 17 and 18 respectively, each of which shafts is journaled at its ends, as at 19 and 20, respectively', upon the frame or base members 13. Each of the sectors 15 v meshes with one of the sectors 16. From veach of the sectors 15 across the center of the shaft 17, extend braced radial arms 21 and 22 respectively-the arms 21 beine` parallel as are also the arms 22, from the ormer of which a pitman 23 extends respectively to the gear wheel 10 of the rotary member A, such vpitman being connected with the respective ends of the arms 21. man 23 is connected at its other end with the arms 21. rllhe pitmen 23 are connected at their other ends with a short shaft 25 extending between the gear wheels 10 at corresponding points adjacent to the peripheries of said gear wheels.

Parallel radial arms 26 extend across the center of the shaft 13, from the toothed sectors 16, the length` of each of which is equivalent to the length of each of the radial arms 22 of the sectors 15. A short shaft 27 extends between the outer ends of the radial arms 22; and a short shaft 28 extends between the outer ends of the radial arms 26.

A cross-head 29 is connected with the up-A per end of the pump sleeve F, thus consti- Vtuting the reciprocatory member C; a stuiftend between the short shaft 23 and the short shaft 33. A short shaft 36 extends between the toothed sectors 15, at points diametrically opposed to the ends of the radial arms 22; and the cross-head 31 carries at each end a short shaft 37 and 38, respectively.

Parallel pitmen 33L extend between the short shaft 36 and the short shaft 37. At points of the toothed sectors 16 diametrically opposed to the ends of the radial arms 26 are located the ends of a short shaft 39 between which and the short shaft 38 of the crosshead 31 extend parallel pitmen 40.

The pathev center ofthe gears 10 than the openings 1which are shown in the drawings as receiving the ends of the shaft 25:-to the end that the throw of the pitman 23, and degree of oscillationof the toothed sectors 15 and 16, may be lessened.

` The operation, method of use and advantages ofthe improved mechanical movement constituting the invention will be readily .understood from the foregoing description, taken 1n connection with. theV accompanying drawings and the followino statement vThe operation of the mechanical movement with respect to actuation of the pump rod E and pump sleeve or hollow pump rod F will be explained, whereby the rotation of the rotary member A is translated into reciprocation of said pump rods or pump rod .and pump sleeve, in opposite directions. 1t vwill be understood that rotation of the rotary member A may be produced by reciprocating each or both of the reciprocatory members B and C, through the translating means D; and that such translated rotary movement or such translated reciprocatory movement may be utilized for the actuation of any mechanism. or part or partsthereof for which such translated and applied movement is adapted.

1n utilizing the mechanical movement for the specific purposes herein treatedl of and disclosed in the drawings, the constantly rotating member A, comprising the two gear wheels 10, cause ythrough their pitmen 23 joint oscillation of both pairs of toothedV sectors 15 and 16, the teeth of each sector 15 meshing with the teeth of the companion sector 16. This joint oscillation causes the pitmen 34 and 35 to vertically reciprocate the cross-head 29, and causes the pitmen 38a and 40 to vertically reciprocate the crosshead 31, such cross-heads moving oppositely simultaneously, and correspondingly actuating the pump rod or sleeve F and the pump rod E respectively. The translation of motion recited is accomplished by the utilization of few parts which operate with slight frictional losses and with that smoothness which is demanded in those services inl which rack and strain and jar are fatal to true and uniform operation. Particularly are these results desirable inconnection with pump operation. Ordinarily, guides are required to hold the reciprocating pump rods and attendant features to their paths of play. The use of such lguides is obviated in practising the invention in connection with pumps, as the reciprocatory members B and C move in straightaway paths, being subject to no influences which tend to deflect them from such courses.

rlhe entire translating mechanism is compact in form and may readily be installed in position at the mouth of a well or in other mechanical environment, without occupation of unnecessary space. The component parts and features are relatively few in number and simple in nature and most of the same may be obtained as stock supplies and materials.

I do not desire to be understood as limiting myself to the particular construction, organization, method of operation or mode of application shown and described; but reserve the right to vary the same, in adapting` the invention to varying conditions of use and service, without departing fromthe spirit of the invention or the terms of the following claims.
